Abstract: A biometric information processing device (1) includes a brain wave detecting unit (10), a control unit (20), and a movement assisting unit (30). The brain wave detecting unit (10) detects biometric information in at least one brain region from among a plurality of brain regions that are selectable in accordance with a body part that is a target of function recovery or function improvement. The control unit (20) determines, based on the detected biometric information, at least one activity state in the brain including the location of the brain region(s) that is (are) activated in a subject while attempting to move the body part, and an activation level of such activated brain region(s). When the control unit (20) determines that the at least one activated state of the brain satisfies a predetermined condition, the movement assisting unit (30) executes a predetermined motion to assist movement of the body part.

Abstract: A cassette holder structure in the information recording and/or reproducing apparatus which comprises a cassette holder supported by a support structure for movement between a cassette receiving position, at which the cassette holder is ready to receive the cassette, and a loaded position at which information can be recorded on or reproduced from the information carrier medium contained in the cassette, a generally elongated elastic releaseable catch member carried by the cassette holder and resiliently engageable with a detent member defined in the cassette, and means operable to disengage the releaseable catch member from the detent member in the cassette when and so long as the cassette holder is in the cassette receiving position and also to cause the releaseable catch member to be engaged with the detent member in the cassette when the cassette holder with the cassette inserted thereinto is moved from the cassette receiving position towards the loaded position.
